(DC) (Rock Creek Park) Join Rock Creek Conservancy, the National Park Service, and Stream Team Leader Keith Krosinsky and Grace MacNeill for a litter removal restoration event in Rock Creek Park. Trash is the visible form of stormwater pollution, a major threat to water quality and park health and its removal makes the parklands cleaner, safer, and more beautiful for all. Event location, directions, and information will be sent from the event leader 48 hours prior to the event.
